Our son-in-law is in the Marine Corps. He is stationed at the Pentagon and was there on that terrible day. He was scheduled for Okinawa this summer for three years, thankfully, accompanied. Now that's on hold, and we don't know from one day to the next. Fortunately, our daughter just goes with the flow - she's been a military wife for many years.
That is the only way to keep peace of mind at times like these, that is for sure. I am so glad that your son-in-law came through that attack on the Pentagon. We had a friend who was lost in it.
